my usb mic worked yesterday and today nobody on discord can hear me. the mic shows up in windows but no green bar moving. help pls
If Windows lists the mic but the level bar stays flat, the app or Windows privacy setting is blocking it. Check mic access, then the input device in Discord.
A mic that appears in Windows but never moves the level bar is almost always blocked from above: either the Windows microphone privacy switch or the wrong input device selected inside the app.
Test the mic in the browser first. If the Mic Test shows a moving level, the hardware is fine and the problem is only inside Discord.
